' 13 Claims.

This invention relates to that class of hair waving in which a so-called permanent wave is imparted to a pre-formed tress of hair by subjecting the tress to the action of a heating chemical, such as calcium oxide, which, when moistenedI will of itself impart a permanent wave to the said tress.

My invention comprises a hair waving pad of no vel construction, said pad having an outer wrapper, an inner wrapper provided with a foldable iiap, an envelope containing a heating chemical, and an inner sheet oi' absorbent material adapted to be moistened and placed between the ilap and envelope for coaction with the heating chemical.

An example of a hair waving pad embodying my invention is represented in the accompanying drawing in which:

Fig. 1 represents an inside plan view of the pad in its unwrapped condition, the inner absorbent sheet being shown at the side of the pad and the inner-wrapper sheet being shownunfolded;

Fig. 2 represents an inside plan view of the pad in its unwrapped condition after the inner wrapper iiap has been perforated and the inner face of the chemical containing envelope hasl been perforated, the inner absorbent sheet being shown interposed between the inner face of the heating chemical containing envelope and the inner wrapper nap;

Fig. 3 represents a side view of the pad wrapped around a wound tress as in use; and

Fig. 4 represents a longitudinal central section through the wrapped pa s The outer wrapper of the self waving pad is denoted by l and is preferably made of non-absorbent material, as for instance paper. 'I'he inner wrapper or backing is denotedby 2 and is preferably made of metal foil, in the form of a strip as shown in the drawing. This inner wrapper is provided with a foldable iiap or y 3, projecting beyond one edge of an envelope I composed of a. perforable impervious material, such as metal foil, which envelope is attached to the inner face of the inner wrapper 2, and contains a heating chemical, such as calcium oxide in powdered form, which chemical, when moistened, will o1' itself generate suflicient heat to impart a so-called permanent wave to a preformed tress when enclosed Within the pad. It will thus be seen that the flap 3, shown as being a part of the wrapper 2, is thereby secured to the chemical containing envelope.

An inner removable sheet 5 of absorbent magenerate sufiicient heat to terial, such as cotton fabric, is arranged to be moistened and inserted between the ap 3 and the envelope 4 after the inner face of the envelope 4 and the folded over flap 3 of the inner wrapper have been perforated. 'I'he pressing of the flap back into place will squeeze the moisture from the wetted inner sheet into the envelope containing the heating chemical.

In practice,d the tress 6 is wound as usual around a mandrel 1. 'I'he tress may be moistened either before or after it is wound, by a suitable waving solution, such for instance as an ammonia solution. The inner face of the impervious envelope l containing the hair waving chemical is perforated as shown at 8, and the folded over flap 3` of the inner wrapper may be perforated at the same time as shown at 9.

The inner sheet 5 is moistened by water or by a suitable hair waving solution, such` as that used for moistening the tress 6.

Either the solution or the self heating chemical within the envelope may be treated to produce the results hereinbefore set forth.

The pad is then wrapped around the preformed tress and is preferably secured in position at the scalp end of the tress by a suitable scalp protecting guard of well known or approved form, such for instance as the self locking guard I0 shown in the accompanying drawing. 'I'he outer end of the pad may be secured around the mandrel 1, as for instance bytwisting the outer wrapper ofthe pad around the same. The exothermic action starts at once because of the application of moisture by the wetted inner sheet 5 ot the pad to the self heating chemical through the perforations in the inner i'ace o1' the impervious envelope. Heat is then set up w'ithin the pad in order to impart a so-called permanent wave to the pre-formed tress without requiring application oi' heat from an outside source. It will be seen that theA outside wrapper of the pad serves to conne the heat to a large extent Within the pad, the'steam generated by the combination of the treating solution with the chemical being permitted to escape through the crimped outer end of the outer wrapper. n

This application is a division of my copending application tiled January 21, 1932, Serial No. 587,890, entitledMethod ofand means for permanently waving hair. A What I claim is: '1. A hair waving pad for enclosing a preformed tress, said pad comprising anouterwrapper, an inner wrapper having a foldable nap, an envelope containing a chemical which, when moistened, will generate sufficient heat to impart a permanent wave to the tress, and an absorbent sheet adapted to be moistened and placed between the flap and envelope.

2. A hair waving pad for enclosing a preformed tress. said pad comprising a non-absorbent outer wrapper, an impervious inner wrapper having a foldable flap, an impervious envelope containing a chemical which, when moistened, will generate sumcient heat to impart a permanent wave to the tress. and an absorbent sheet adapted to be molstened and placed between the flap and envelope, said nap and envelope being perforable.

3'. A hair waving pad for enclosing a preformed tress, said pad comprising an outer wrapper, an envelope containing an -exothermic material, an inner wrapper, and an intermediate absorbent .sheet interposed between the envelope and the inner wrapper.

, 4. A hair waving pad for enclosinga preformed tress, said pad comprising a non-absorbent outer wrapper, a perforably impervious envelope containing an exothermic material, an inner impervious wrapper, and a moistenable intermediate absorbent sheet interposed between Vthe envelope and the inner wrapper.

5. A hair waving pad for enclosing a preformed tress, said pad comprising a non-absorbent outer wrapper, a perforable impervious envelope cc itaining an exothermic material, a perforable inner impervious wrapper, and a moistenable intermediate absorbent sheet interposed between the envelope and the inner wrapper.

6. A hair waving pad for enclosing a preformed tress, said pad comprising an outer wrapper of paper, an envelope of metal foil containing an exothermic material, an inner wrapper `of metal foil, and an intermediate sheet of absorbent material.

'1. A vhair waving pad. for enclosing a preformed trees, said pad comprising an outer wrapper of paper, a perforable envelope of metal foil containing an exothermic material, a perforable inner wrapper of metal foil, and a moistenable intermediate sheet of obsorbent material.

8. A hair waving pad comprising a flexible metallic container, a chemical therein adapted to produce heat when contacted with moisture, a member adapted to absorb moisture and a metallic nap projecting at one edge of the container and ladapted to be folded thereover.

9. A hair waving pad comprising a flexible metallic container, a chemical therein, adapted to produce heat when contacted withmoisture, means to apply moisture to the chemical, said means comprising a member adapted to be liquid impregnated and a metallic fiap projecting at one edge of the container and adapted to overlie the liquid impregnated member.

10. A sachet for permanent waving of hair comprising a wrapper, a backing secured to said wrapper, an envelope mounted on said backing and having a chemical therein, a fly secured to said backing and foldable along one edge of said envelope to overlie the surface thereof, said fly and the corresponding surface of said envelope being perforate and a moistening member disposed between said fly and envelope and impregnated with a liquid for infusion into the chemical in said envelope.
